Non-linear Graphs and Graphical Solutions
Recognise, sketch and solve using quadratic, cubic, reciprocal, exponential, circular and trigonometric graphs.
How to study for GCSE Mathematics
Use 601 original multiple-choice questions to learn connected methods, explain why they work, practise exact non-calculator execution and use a calculator strategically on designated papers.
Core concepts
Concept 1
Quadratic and cubic graphs
Exam cue: Use intercepts, symmetry, turning points and end behaviour, then read solutions from intersections with the required line or curve.
Concept 2
Reciprocal and exponential graphs
Exam cue: Substitute approximate intersection coordinates and confirm they satisfy both relationships to graph-reading accuracy.
Concept 3
Intersections and graphical solutions
Exam cue: Represent the information clearly, choose a justified method and communicate each step with correct notation and units.
Targeted study blocks
Tier coverage
Foundation core with Higher-tier extensions
Higher includes reciprocal and exponential graphs, trigonometric graphs, circle equations, tangent reasoning and more demanding graphical solution and transformation work.
Calculator structure
Prepare for calculator and non-calculator papers
Any part of a board's specification may be assessed on any paper. Non-calculator does not define a smaller syllabus; questions are designed so exact arithmetic and reasoning are feasible without a calculator.
Risk pitfalls and guardrails
Reading only one intersection when the graphs meet more than once.
Guardrail: Do not hide an invalid model behind arithmetic: check assumptions, signs, bounds, units, scale, required accuracy and the original question.
Giving an unsupported answer when the command requires working, proof, reasoning or interpretation.
Guardrail: Do not hide an invalid model behind arithmetic: check assumptions, signs, bounds, units, scale, required accuracy and the original question.

Memory anchors
Graphical equation solution
The x-coordinate of an appropriate intersection.
Quadratic roots
The x-intercepts where y = 0.
Equation of a circle
(x − a)² + (y − b)² = r².
Non-linear Graphs and Graphical Solutions: method
Use intercepts, symmetry, turning points and end behaviour, then read solutions from intersections with the required line or curve.
Non-linear Graphs and Graphical Solutions: check
Substitute approximate intersection coordinates and confirm they satisfy both relationships to graph-reading accuracy.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
